An international team of researchers has made a breakthrough discovery about how pancreatic cancer cells use the host's own immune system to stealthily grow. By blocking this mechanism, the scientists were able to shrink pancreatic tumors by 94% in laboratory animals, raising hopes for new treatments for one of the deadliest forms of cancer.

Why it matters

Pancreatic cancer is the 11th most common cancer but the third leading cause of cancer deaths in the U.S., killing around 52,000 Americans in 2025. It is often considered a death sentence due to its aggressive nature and lack of effective screening and treatment options. This discovery could lead to new therapies to combat this devastating disease.

The details

The researchers, from the University of Würzburg, Würzburg University Hospital in Germany, and the Massachusetts Institute of Technology, found that pancreatic cancer cells are able to hijack the body's immune system to fuel their own growth. By blocking this mechanism, they were able to dramatically shrink pancreatic tumors in laboratory animals.

• The findings were published in the peer-reviewed journal Cell on January 22, 2026.
